Specification of Letters Patent. Pamted Aue-u 22 1922.

.application med october 25, issn;l serial ne 510,265.A

do hereby declare the following to be a full,

clear, and

and ars without the annoyance and expense of punctures and blow-outs attached to pneumatic tires.

Another object of this invention is the provisionof an inner tube vthat may be easilyr and quickly assembledjand disassembled to permit changing of any onev of the parts when worn or broken and which willbe simple, durable and eicient, and which maybe manufactured and soldat a comparatively low cost. .y

With these and other objects in View as will become more apparent as the description proceeds, the invention consistsin certain novel features of construction, combination, and arrangementof parts'as will be hereinafter more fullydescribed and claimed.

For a complete understanding of my invention, reference is to be had to the following description, and accompanying drawings, in which Figure 1 is a transverse sectional view illustrating my invention applied to a shoe and the latter mounted on a rim,

Figure 2 is longitudinal sectional view illustrating` my invention in the shoe,

Figure 3 is a fragmentary plan view illustrating the cushioning means and showing in dotted lines a part ot the casing. f

Figure l is a fragmentary side elevation, illustrating the manner of connecting the inner and outer bands and also the side plates.

Figure 5 is a detail sectional view, illustrating a portion of the casing which may exact description of the invention," v such as will enable others skilled in the art for its primary" strain and `which I will proy bebentbaclr upon the casing to permit fastening of the ends of the outer band.v

nleferring in detail to the drawingsfthenumeral 1 indicates a cushioning means that .includes inner and outer circumferentially extending flexible bands 2 and?) constructed from steelor any `other material suitable for the purpose. l rEhe bands 2 and-3 have their edges bent to Vform flanges el thatare notched at spaced intervals as shown at to vpermit lering of the band. The outer band 3 has its ends detachably connected by a platef.

The plate 6 ,has rivets? that extend throughvv openings in theband adjacent its ends. The plate 6 has formed integrally therewith a pin S that extends through notches 9 termed in the ends of the inner band 2` yThe bands @fand 3 at spaced vintervals are provided with pins 10 to form spring seats and project inthe ends of coil springs 1l, the springs 11 are positioned between the inner and outer bands and are tapered towards one of their 4ends. The springs yhave their smaller ends in contact with the inner band, while y their larger ends contact `with the outerl band.v n i f nplurality of side plates 12 have their outer and inner edges curved inwardly as illustrated at 13 and are fastened to the 'flanges of the inner and outer bands 2 and 3 by fastening elements 14.. The fastening ele'i'nents le are of any desired construction and are ca'pableof permitting theuside plates to be detached from the inner and outer bands when desired. 4The ends of thel vside plates. slightlyove'rlap .each other and are pivotally connected by rivets or similar fasteners 15. The plates have formed thereon pins 16 that form seats for transversely arranged springs 17 that extend between the springs 11 and are of coil formation. The pins 16 proj ect a short distance into the ends f the springs 17 to prevent said springs from accidentally disengaging the plates 12 during the use of the device.

The pin or rod 8 formed on the connecting plate 6 also has a spring 11 mounted thereon and which spring bears against the connecting plate 6 and the notched ends of the inner band. The pin or rod 8 extends through the rim 18 and the felly 19 of a wheel and has a nut 2O turned thereon. The rim forms the subject matter of a co-pending application filed October 1, 1921, and serially numbered 504,566. The cushion OF ONE-THIRD TO'MILTQN means l after assembled is placed within a casing,251i` Constructed of rubber'or' any other material suitable for the purpose. The casing 21 is severed at its ends to permit portions 2l of said casing to be turned back so that the ends of the outer band may be connected and the pin or rod 8 passed through the notched ends 9 ofA the inner band. The pin or rod `@passes through the casing 21 and ythen' 'thr.ou'gh the rim and felly a's before described. The casing 2l has placed` against its interior wall filler elements '23 to 'form seats `for the inner and outer" bands and side plates to engage, and are preferably constructed of rubber to increase' the resiliency of the device. After thedevice has been assembled in the casing 21, the latter is positioned within an` ordinary shoe 22 `in a manner similar to the placing of an ordinary inflatable tube withinashoe.l 'v

`While I'liave' shown and describedthe preferred embodiment of my invention,'it will be' understood that minor changes in construction, combination, and `arrangement of parts may be made without departing from the spiritandscope of 'theinvent'ion afsdamed.

Having thus ldescribe'l my invention what I claim iszy f l. Al'clushion inner .tube comprising inner andY oute'ry` circu-mferentially l extending bands, cushioning means between said bands, side plates rconnectedto the inner andl outer I bands, and cushioning meansbetWeen` thel "2. A cushion inner tube comprising inner and outer bands, means connecting. the ends n of .the 'bands together, cushioning means be-, tween said bands, a plurality of side plates -pivotally connected to each other and lieX ibl'yy connected to the inner and louter bands,

and v'cushioning means between the 'side` plates.

3a. A cushion inner tube comprising inner and outer bands, pins secured to saidbands at spaced intervals, coil springs engaging saidv .hands and receiving the pins inthe,

ends thereof, pivotally connected side plates flexibly connected to the inner and outer bands, pins secured to said sidey plates, and

coil springs bearing against the side lplates andrece'iving the'last named pins in Vthe `ends thereof.

4'. A cushioninner tube comprising inner and outer bands having their edges bent to form flanges, said fianges notched at spaced intervals, springs interposed between the inner and outer bands, pivotally connected` side plates `flexibly connected tothe flanges and having their edges bent to form flanges,

` and outer bands, cushioning means betweenv said bands, side plates connected to said bands, cushioning means between said plates,

la casing receiving said inner `and outer bands and plates and ylosing severed at its ends to permit vportions of'said casing'to be `bent upon the casing, an` attaching platek connecting the ends of the outer band, said inner band having its ends notched, a pin carried by said attaching plate and extending through thevnotched ends of the inner band and through the casing and adapted to pass through the riml and el'lyy of the wheelv and have a nut turned thereon.

In testimony whereof I aflix my signaturey in presence of two witnesses.' l
